Re: PYI PSS shaft seal bellows replacement on Crealock 37
You'll need to get the coupling off the shaft, remove the PYI collar and retract the shaft far enough to R&R the bellows.. whether the prop needs to come off depend in it's configuration and any interference with the rudder as far as creating enough space to do that.
Careful about any burrs on the keyslot/coupling area when you slide the collar off and back on; You'll want to replace the orings and set screws on the collar with new too.
The link is for new installs, but worth the read:
